ipq40xx: set MAC address for AVM boxes at preinit

Usually the bootloader configures the MAC address of the ethernet
interfaces. However newer boxes do not have the MAC address and relevant
pointers in their bootloader partition anymore, hence boxes end up with
random addresses on every boot.

Obtain the MAC address from the TFFS and assign it to the ethernet
interface at preinit.
